Cleveland C80427 5-Flute Carbide End Mill
The Cleveland C80427 is a solid carbide square end mill designed for milling steel. Its five-flute geometry and TiAlN coating suit machinists and metalworking shops that need reliable material removal in ferrous alloys. The 1/4-inch shank fits standard collets and holders used in CNC and manual milling machines.
Sustained cutting in steel with TiAlN protection
The TiAlN coating resists heat buildup during extended passes, allowing the five flutes to maintain edge integrity longer than uncooled tools. Carbide construction provides stiffness that reduces deflection when the 0.75-inch length of cut engages deep slots or profiles. Non-coolant-through design means chips evacuate through flute channels rather than internal passages.
0.25-inch diameter decides the application
A cutting diameter of .25 in determines the minimum feature size and step-over possible in steel workpieces. The 2-1/2-inch overall length sets the reach from the holder face to the tip. Buyers needing larger diameters or longer reach for deeper cavities must select a different tool.

Questions about this item
How much heat and noise does the 5-flute carbide end mill generate during extended cutting?
The tool itself produces no noise or heat; those come from the spindle and workpiece. Carbide with TiAlN coating runs cooler than uncoated steel cutters, reducing thermal load on the machine.
What holder or collet is required to run the 1/4 in shank on my milling machine?
Use a 1/4 in straight-shank collet, ER collet reduced to 1/4 in, or a 1/4 in end-mill holder that matches your spindle taper.
Will the 0.25 in diameter cutter work with the lower spindle speeds on my older knee mill?
Yes — the 5-flute geometry and TiAlN coating allow efficient cutting at modest RPMs typical of older machines, though feed rates should be reduced accordingly.
